C program to print Pascal triangle using For Loop

Here is source code of the C program to print Pascal triangle using For Loop. The C program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.

SOURCE CODE : :

/*  C program to print Pascal triangle using For Loop  */

#include<stdio.h>
 
long fact(int);
int main(){
    int line,i,j;
 
    printf("Enter the no. of lines: ");
    scanf("%d",&line);
 
    for(i=0;i<line;i++){
         for(j=0;j<line-i-1;j++)
             printf(" ");
 
         for(j=0;j<=i;j++)
             printf("%ld ",fact(i)/(fact(j)*fact(i-j)));
         printf("\n");
    }
    return 0;
}
 
long fact(int num){
    long f=1;
    int i=1;
    while(i<=num){
         f=f*i;
         i++;
  }
  return f;
 }

Output :

/*  C program to print Pascal triangle using For Loop  */
